Please help diagnose

Two weeks ago the car stalled out of nowhere. Tried starting the car over and over and it wouldn't. Checked that the engine was getting fuel, checked the plugs and COPs and didn't see any issues there. I decided to reload the tune and the car started right up. I thought the problem was over. I drove the car to work all last week with no issues except for a searching idle.

First thing I would do is make absolute certain the maf and throttle body are clean. Other than that it's hard to say...maybe a problem with the tune?? Have you checked for codes?

Check alternator !

Many threads on alternaters gone bad with similar symptoms.

Brand new alternator. Maf and TB are clean. I guess I double posted this thread. I replaced the spark plugs and all is well again. Runs like a champ.
